You must install a valid license to use the MDC feature. When the license expires or is uninstalled, you cannot create, start, or use non-default MDCs. For more information about licenses, see Fundamental Configuration Guide.

Do not configure MDCs on a device installed with the LSQ series OAP modules, or install LSQ series OAP modules on a device configured with MDCs.

MDC commands for the default MDC

This section describes the MDC commands that you can use after logging in to the default MDC (the physical device).

Unless otherwise stated, the term "MDC" in this section refers to a non-default MDC.

allocate interface

Use allocate interface to assign a physical interface to an MDC.

Use undo allocate interface to reclaim a physical interface assigned to an MDC.

Syntax

allocate interface { interface-type interface-number }&<1-24>

undo allocate interface { interface-type interface-number }&<1-24>

allocate interface interface-type interface-number1 to interface-type interface-number2

undo allocate interface interface-type interface-number1 to interface-type interface-number2

Default

All physical interfaces on the device belong to the default MDC. A non-default MDC cannot use any physical interfaces.

Views

Predefined user roles

network-admin

mdc-admin

Parameters

{ interface-type interface-number }&<1-24>: Specifies a space-separated list of up to 24 interfaces.

interface-type interface-number1 to interface-type interface-number2: Specifies a range of interfaces. The two interface-type arguments must have the same value. All interfaces in the range must be on the same LPU.

Usage guidelines

You can assign multiple physical interfaces to a non-default MDC. A physical interface must meet the following requirements to be assigned to a non-default MDC:

· The interface must belong to the default MDC. To assign a physical interface that belongs to one non-default MDC to another non-default MDC, you must remove the existing assignment by using the undo allocate interface command.

· The interface must not be the console port. The console port of the device belongs to the default MDC. You cannot assign them to a non-default MDC.

· The interface must not be the management Ethernet interface. The physical management Ethernet interface of the device belongs to the default MDC and cannot be assigned to a non-default MDC. When a non-default MDC is created, the system automatically creates a virtual management Ethernet interface for the MDC. All the virtual management Ethernet interfaces use the same interface type and number and the same physical port and link as the default MDC's physical management Ethernet interface. However, you must assign different IP addresses to the virtual management Ethernet interfaces so MDC administrators can access and manage their respective MDCs. The IP addresses for the management Ethernet interfaces do not need to belong to the same network segment.

When you assign physical interfaces on an IRF member device to MDCs, make sure the default MDC always has one or more physical IRF ports in up state. Assigning the default MDC's last physical IRF port in up state to a non-default MDC splits the IRF fabric.

Assigning or reclaiming a physical interface restores the settings of the interface to the defaults. If the MDC administrator configures the interface during the assigning or reclaiming operation, settings made before the operation is completed are lost.

To configure a physical interface assigned to an MDC, you must log in to the MDC.

Examples

# Assign interfaces GigabitEthernet 1/0/1 and GigabitEthernet 1/0/3 to MDC sub1.

<Sysname> system-view

[Sysname] mdc sub1

[Sysname-mdc-2-sub1] allocate interface gigabitethernet 1/0/1 gigabitethernet 1/0/3

Configuration of the interfaces will be lost. Continue? [Y/N]:y

# Assign interfaces GigabitEthernet 1/0/1 through GigabitEthernet 1/0/8 to MDC sub1.

<Sysname> system-view

[Sysname] mdc sub1

[Sysname-mdc-2-sub1] allocate interface gigabitethernet 1/0/1 to gigabitethernet 1/0/8

Configuration of the interfaces will be lost. Continue? [Y/N]:y

# Assign interface GigabitEthernet 1/0/4 to MDC sub1.

<Sysname> system-view

[Sysname] mdc sub1

[Sysname-mdc-2-sub1] allocate interface gigabitethernet 1/0/4

Configuration of the interfaces will be lost. Continue? [Y/N]:y

Group error: all interfaces of one group must be allocated to the same mdc.

Gigabitethernet1/0/4

Port list of group 2:

GigabitEthernet1/0/3 GigabitEthernet1/0/4

The output shows that GigabitEthernet 1/0/4 and GigabitEthernet 1/0/3 belong to the same group and must be assigned to the same MDC at the same time. To assign both interfaces to MDC sub1, use the following command:

[Sysname-mdc-2-sub1] allocate interface gigabitethernet 1/0/3 gigabitethernet 1/0/4

Configuration of the interfaces will be lost. Continue? [Y/N]:y

limit-resource cpu

Use limit-resource cpu to specify a CPU weight for an MDC.

Use undo limit-resource cpu to restore the default.

Syntax

limit-resource cpu weight weight-value

undo limit-resource cpu

Default

The default MDC has a CPU weight of 10 on each MPU. Each non-default MDC has a CPU weight of 10 on each MPU.

Views

MDC view of a non-default MDC

Predefined user roles

network-admin

mdc-admin

Parameters

weight weight-value: Specifies a CPU weight value in the range of 1 to 10.

Usage guidelines

The amount of CPU resources available for an MDC depends on the CPU weight settings for all MDCs that share the same CPU. For example, if three MDCs share the same CPU, setting their weights to 10, 10, and 5 is equivalent to setting their weights to 2, 2, and 1.

· The two MDCs with the same weight can use the CPU for approximately the same period of time.

· The third MDC can use the CPU for about half of the time for each of the other two MDCs.

The CPU weight for the default MDC is fixed at 10. You cannot change it.

Examples

# Set the CPU weight of MDC sub1 to 2.

<Sysname> system-view

[Sysname] mdc sub1

[Sysname-mdc-2-sub1] limit-resource cpu weight 2

limit-resource disk

Use limit-resource disk to specify a disk space percentage for an MDC.

Use undo limit-resource disk to restore the default.

Syntax

In standalone mode:

limit-resource disk slot slot-number [ cpu cpu-number ] ratio limit-ratio

undo limit-resource disk slot slot-number [ cpu cpu-number ]

In IRF mode:

limit-resource disk chassis chassis-number slot slot-number [ cpu cpu-number ] ratio limit-ratio

undo limit-resource disk chassis chassis-number slot slot-number [ cpu cpu-number ]

Default

All MDCs share the disk space in the system, and an MDC can use all free disk space in the system.

Views

Predefined user roles

network-admin

mdc-admin

Parameters

slot slot-number: Specifies an MPU. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies an MPU on an IRF member device. (In IRF mode.)

cpu cpu-number: Specifies a CPU by its number. If you do not specify this option, the command specifies a disk space percentage for CPU 0.

ratio limit-ratio: Specifies the ratio of the disk space an MDC can use on the specified card to the total disk space of the card. The value range is 1 to 100.

Usage guidelines

Before you specify a disk space percentage for an MDC, use the display mdc resource command to view how much disk space the MDC is using. Make sure the disk space you assign to an MDC is greater than the disk space the MDC is using. Otherwise, the MDC cannot apply for more disk space and no additional folders or files can be created or saved for the MDC.

Examples

# (In standalone mode.) Allow MDC sub1 to use up to 30 percent of the disk space on the MPU in slot 1.

<Sysname> system-view

[Sysname] mdc sub1

[Sysname-mdc-2-sub1] limit-resource disk slot 1 ratio 30

# (In IRF mode.) Allow MDC sub1 to use up to 30 percent of the disk space on the MPU in slot 1 on IRF member device 2.

<Sysname> system-view

[Sysname] mdc sub1

[Sysname-mdc-2-sub1] limit-resource disk chassis 2 slot 1 ratio 30

limit-resource memory

Use limit-resource memory to specify a memory space percentage for an MDC.

Use undo limit-resource memory to restore the default.

Syntax

In standalone mode:

limit-resource memory slot slot-number [ cpu cpu-number ] ratio limit-ratio

undo limit-resource memory slot slot-number [ cpu cpu-number ]

In IRF mode:

limit-resource memory chassis chassis-number slot slot-number [ cpu cpu-number ] ratio limit-ratio

undo limit-resource memory chassis chassis-number slot slot-number [ cpu cpu-number ]

Default

All MDCs share the memory space in the system, and an MDC can use all free memory space in the system.

Parameters

slot slot-number: Specifies a card. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device. (In IRF mode.)

cpu cpu-number: Specifies a CPU by its number. If you do not specify this option, the command specifies a memory space percentage for CPU 0.

ratio limit-ratio: Specifies the ratio of the memory space that an MDC can use on the specified card to the total memory space of the card. The value range is 1 to 100.

Usage guidelines

This command sets the maximum amount of memory space that an MDC can use. Make sure this amount is sufficient for the MDC to operate correctly.

Examples

# (In standalone mode.) Allow MDC sub1 to use up to 30 percent of the memory space on the card in slot 1.

<Sysname> system-view

[Sysname] mdc sub1

[Sysname-mdc-2-sub1] limit-resource memory slot 1 ratio 30

Parameters

slot slot-number: Specifies an LPU. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies an LPU on an IRF member device. (In IRF mode.)

Usage guidelines

To assign physical interfaces to an MDC, you must authorize the MDC to use the LPUs to which the physical interfaces belong.

To return an LPU that has been assigned to a non-default MDC to the default MDC, you must perform the following tasks:

1. Use the undo location command to reclaim the LPU.

2. Use the location command to assign the LPU to the default MDC.

Examples

# (In standalone mode.) Authorize MDC sub1 to use the LPU in slot 3.

<Sysname> system-view

[Sysname] mdc sub1

[Sysname-mdc-2-sub1] location slot 3

# (In IRF mode.) Authorize MDC sub1 to use the LPU in slot 3 on IRF member device 2.

Parameters

mdc-name: Specifies the MDC name, a case-sensitive string of 1 to 15 characters.

id mdc-id: Specifies the MDC ID. The value range is 1 to 9. If you do not specify this option, the system assigns the lowest ID number among the available IDs to the MDC.

Usage guidelines

The default MDC is system defined. You cannot delete it.

A switch that uses the MPUs supports up to four non-default MDCs. A switch that uses other MPUs supports up to eight non-default MDCs.

Predefined user roles

network-admin

Usage guidelines

After an MDC is started, administrators of the MDC can log in to the MDC for MDC configuration and maintenance.

Stop an MDC with caution. Stopping an MDC interrupts all services on the MDC and logs out all login users on the MDC.

To avoid configuration loss, save the running configuration of an MDC before stopping the MDC.

Examples

# Start MDC sub1.

<Sysname> system-view

[Sysname] mdc sub1

[Sysname-mdc-2-sub1] mdc start

It will take some time to start MDC...
